I did. Just forgot to place the decimal.

I did. Just forgot to place the decimal.

yeah I thought you must have missed dividing
My question remains why not compound it?
why not multiply by 1115/100 3 times?

Correct to 1 decimal place, that is, 0.1. Now in 100 grams of beans there is 1+0.05 = 1.05 grams of salt (upper bound)
So in 210 grams of beans there will be 210*1.05/100 grams of salt.
